Acids and Bases

Acids and Bases

an acid is a chemical compound that has extra hydrogen ions that it can loose. We found that when an acid is mixed with a base, a salt and water is produced. on the P.H. scale which is the standard way of measuring acids and bases the acids are between 0 and 6.9 and bases are from 7.1 to 14. so that means that 7 is neutral.

salts are a neutral compound which is not table salt excluding the first experiment.
these are the results we have for the tests we did:

• hydrochloric acid + sodium hydroxide = sodium chloride + water 

HCl + NaOH = NaCl +H2O

• hydrochloric acid + magnesium oxide = magnesium chloride + water

2HCl + MgO = MgCl2 + H2O

• nitric acid + sodium hydroxide = sodium nitrate + water

HNO3 + NaOH = NaNO3 + H2O

• nitric acid + magnesium oxide = magnesium nitrate + water

2HNO3 + MgO = Mg(NO3)2 + H2O

• sulfuric acid + sodium hydroxide = sodium sulfate + water

H2SO4 + NaOH = Na2SO4 +H2O this is not balanced

• sulfuric acid + magnesium oxide = magnesium sulfate + water

H2SO4 + MgO = MgSO4 + H2O

• ethanoic acid + sodium hydroxide = sodium ethanoate  + water

CH3COOH + NaOH = NaCH3COO + H2O

• ethanoic acid + magnesium oxide = magnesium ethanoate + water

2CH3COOH  + MgO = Mg(CH3COO)2 + H2O

• therefore
• acid + base = salt(not table salt) + water
